  • EmuFlight and INAV Matrix Filter

    Matrix Filter will have its premiere together with EmuFlight 0.3.0 and INAV 2.5. Which of those two will happen first is still unknown.

  • INAV on rovers, boats, crawlers, tanks and other ground vehicles

    What can INAV do? Well…. it can fly your multirotor drone and a fixed-wing airplane. And it can do it pretty nicely! Unfortunately, that is all it can do. Now, at least. Every year or so, I’m building an RC airboat and always wanted to build a rover based on some kind of an RC…

Sometimes, tho, it’s so hilartious… Like today I learned that I was disqualified from… Yes, from what? Betaflight? Some other…

  • FrSky Taranis Q X7 and X7S – is it still worthy?

    FrSky Taranis QX7 appeared on the market a few years ago and got quite a lot of popularity in its time. There were reasons for that:

  • Dalprop Nepal N1 5" propellers

    This weekend, thanks to Foxeer, I had an opportunity to test flight new Dalprop freestyle props: Nepal N1. Although the name is a puzzle for me, I’m pretty sure Dalprop Nepal N1 might make some stirr!
